Traditional fault detection methods rely on threshold-based or impedance-based approaches that require extensive domain expertise and often fail under dynamic operating conditions or noisy environments. This study presents a hybrid deep learning approach that combines Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) architectures to automatically learn spatial and temporal patterns in electrical fault data. The CNN component extracts discriminative spatial features from multivariate time-series measurements of three-phase current and voltage, while the LSTM component captures temporal dependencies within fault signal windows. The model was trained, validated, and tested using an open-source electrical fault dataset from Kaggle containing 7,861 labeled samples across six fault classes: No Fault, Line-to-Ground (LG), Line-to-Line (LL), Line-to-Line-to-Ground (LLG), Three-Phase (LLL), and Three-Phase with Ground (LLLG). Results demonstrate an overall accuracy of 78.01%, precision of 77.53%, recall of 78.01%, and F1-score of 77.47%, with notable performance in identifying line-to-ground faults. Performance metrics were supplemented with confusion matrices, ROC curves, precision-recall curves, and learning curves. Comparative analysis with existing literature demonstrates that hybrid CNN-LSTM models improve classification accuracy over standalone networks in similar applications. The study concludes that CNN–LSTM hybrid architectures provide an effective framework for automated fault diagnostics in power systems and recommends future work on larger datasets, attention mechanisms, and integration with real-time grid monitoring systems."""
